PURPOSE: to describe the maternal complications due to therapeutic endoscopic procedures in fetal Medicine performed at an university center in Brazil. METHODS: retrospective observational study including patients treated from April 2007 to May 2010 who underwent laser ablation of placental vessels (LAPV) for severe twin-twin transfusion syndrome (TTTS); fetal tracheal occlusion (FETO) and endoscopic removal of tracheal balloon in cases of severe congenital diaphragmatic hernia (CDH); LAPV with or without bipolar coagulation of the umbilical cord in cases of twin reversed arterial perfusion (TRAP) sequence. The main variables described for each disease/type of surgery were maternal complications and neonatal survival (discharge from nursery). RESULTS: fifty-six patients underwent 70 procedures: Severe TTTS (34 patients; 34 surgeries); severe CDH (16 patients; 30 surgeries), and TRAP sequence (6 patients; 6 surgeries). Among 34 women who underwent LAPV for TTTS, two (2/34=5.9%) experienced amniotic fluid leakage to the peritoneal cavity and seven (7/34=20.6%) miscarried after the procedure. Survival of at least one twin was 64.7% (22/34). Among 30 interventions performed in cases of CDH, there was amniotic fluid leakage into the maternal peritoneal cavity in one patient (1/30=3.3%) and premature preterm rupture of membranes after three (3/30=30%) fetoscopies for removal of the tracheal balloon. Infant survival with discharge from nursery was 43.8% (7/16). Among six cases of TRAP sequence, there was bleeding into the peritoneal cavity after surgery in one patient (1/6=16.7%) and neonatal survival with discharge from nursery was 50% (3/6). CONCLUSIONS: in agreement with the available data in literature, at our center, the benefits related to therapeutic endoscopic interventions for TTTS, CDH and TRAP sequence seem to overcome the risks of maternal complications, which were rarely considered severe.

The objective of this study was to identify the perspective of the specialists about functioning in women with cervical cancer (CC).
A study was conducted with specialists using the Delphi methodology. The specialist contacts were found in oncology organizations and associations, as well as in a referral hospital in the treatment of CC. The questions that the experts answered covered the biopsychosocial domains of the International Classification of Functioning, Disability and Health (ICF).
Twenty-five specialists participated in the study. The experts’ responses generated 485 significant concepts. The categories that presented the highest frequencies of reporting by the specialists were health services, systems and policies; structure of the reproductive system; health professionals and sexual function.
Regarding the perception of the specialists, this study concluded that 24 categories of ICF are the most relevant in the context of functioning in women with CC. The results suggest that the biopsychosocial perspective was incorporated in the experts’ perceptions about the functioning phenomenon in women with CC in Brazil.

PURPOSE: to evaluate Doppler velocimetry of the ductus venosus as a noninvasive test of abnormal pH and gas analysis in preterm fetuses with "brain sparing reflex". METHODS: a cross-sectional study was performed. The studied population consisted of 48 pregnant women between the 25th and the 33rd week of gestation, whose fetuses presented brain sparing reflex (umbilical/cerebral ratio >1). The time elapsed between Doppler velocimetry and the birth (cesarean section under peridural anesthesia) was of up to 5 h. The following parameters were studied: S/A ratio of the ductus venosus, pH and base excess (BE) of fetal blood sample (collected from the umbilical vein immediately after birth). The S/A ratio of the ductus venosus was considered abnormal when superior to 3.6. The fetuses were classified according to the gas analysis result. They were considered abnormal when pH <7.26 and BE £ 6 mMol/L. Fisher's test was used for statistical analysis and considered significant when p £ 0.05. RESULTS: there was a significant correlation between umbilical blood gas analysis in preterm fetuses with brain sparing reflex and ductus venosus S/A ratio (p = 0.0000082; Fisher test). Ductus venosus Doppler velocimetry identified 10 of 14 fetuses with abnormal gas analysis. On the other hand, 32 of 34 fetuses with normal gas analysis were correctly identified. The sensitivity of the ductus venosus S/A ratio for the diagnosis of abnormal blood gas analysis was 71%, specificity 94%, false-negative rate 8%, false-positive rate 4%, positive predictive value 83% and negative predictive value 89%. Pretest likelihood, post-test posterior probability following a positive test result (post-test likelihood) and post-test posterior probability following a negative test result (post-test likelihood) were 31, 84 and 10%, respectively. CONCLUSION: the analysis of the ductus venosus S/A ratio is adequate for the diagnosis of abnormal blood gas analysis in preterm fetuses presenting brain sparing reflex.

, , , , , , To determine the existence of SARS-CoV-2 in the peritoneal fluid to assess the risk of exposure through surgical smoke and aerosolization threatening healthcare workers during abdominal surgery.
SARS-CoV-2 is a respiratory virus and possible ways of viral transmission are respiratory droplets, close contact, and fecal-oral route. Surgeries pose risk for healthcare workers due to the close contact with patients. Aerosolized particles may be inhaled via the leaked CO2 during laparoscopic procedures and surgical smoke produced by electrocautery.
All the data of 8 patients, who were tested positive for COVID–19, were collected between August 31, 2020 and April 30, 2021. Recorded clinicopathologic data included age, symptoms, radiological and laboratory findings, antiviral treatment before surgery, type of surgery and existence of the virus in the peritoneal fluid. Nasopharyngeal swab RT-PCR was used for the diagnosis. COVID–19 existence in the peritoneal fluid was determined by RT-PCR test as well.
All 8 COVID–19 positive patients were pregnant, and surgeries were cesarean sections. 1 of the 8 patients was febrile during surgery. Also only 1 patient had pulmonary radiological findings specifically indicating COVID-19 infection. Laboratory findings were as follows: 4 of 8 had lymphopenia and all had elevated D-dimer levels. Peritoneal and amniotic fluid samples of all patients were negative for SARS-CoV-2.
SARS-CoV-2 exposure due to aerosolization or surgical fumes does not seem to be likely, provided the necessary precautions are taken.

The polycystic ovaries syndrome (POS) is a heterogeneous endocrinal disorder prevalent in 5 to 10% of women in reproductive age. In POS, there is an association with risk factors linked to the development of cardiovascular disease such as insulin resistance, dislipidemia, diabetes mellitus, arterial hypertension, endothelial dysfunction, central obesity, metabolic syndrome and chronic pro-inflammatory markers. Physical exercise practice together with nutritional guidance have been recommended as first rate strategies in the treatment of oligomenorrhea, hirsutism, infertility and obesity in POS women. This way, the objective of the present review was to analyze the specific role played by exercise and/or physical activity in changes of the body shape, in biochemical and hormonal plasmatic levels, and in the POS women’s reproductive function.
